Question

Kaitlyn creates an architectural blueprint of a rectangular dining room.The area of the actual dining room is 900 times as large as the area of the dining room on the blueprint.The length of the dining room on the blueprint is 4 inches.What is the length of the actual dining room?

Answer 1

Well, since the actual size is 900 times as large as the size in blueprint, this would probably be division.  If I'm right, you would first do 900 divide by 4 would equal to 225.  so the actual size of the dining room is 225.
I hope this helps...
